SPECIAL FEATURES & FUNCTIONS

IMPORTANT WARNINGS

• NEVER place the charger or battery on a flammable surface or near a flammable object while in use. Keep away fromcarpets, cluttered workbenches, etc.

• NEVER overcharge batteries as permanent damage could result. Do not use a charge or discharge current rate whichexceeds the safe level of the battery. Do not attempt to charge or discharge a battery if it is hot.

• ALWAYS disconnect from power source when not in use.• ALWAYS keep out of reach of children.• ALWAYS connect the charge lead to the charger before connecting the battery to the lead. And ALWAYS disconnect the

battery from the charge lead BEFORE disconnecting the charge lead from the charger. Otherwise, if the ends of the chargelead touch each other while the battery is still connected it will cause a severe and dangerous short-circuit condition.

G

Amps (A): The unit of measure for charge or discharge current.

Milli-amps (mA): A unit of measure for current, being amps (A) multiplied by 1000 and listed as “mA”. So 2.5A is the sameas 2500mA (2.5 x 1000). Or, to convert mA to amps, divide the mA number by 1000. So 25mA is the same as 0.025A (25divided by 1000).

Capacity, milli-amp hours (mAh), and amp-hours (Ah): Charge energy stored by a battery is called capacity, which isdefined as how much current a battery can supply in one hour of time. Most hobby batteries are rated for capacity in “mAh”or milli-amp hours. A 650mAh battery can deliver 650mA of current for one hour (650mA x 1hr = 650mAh). A 3200mAhbattery can deliver 3200mA (3.2A) of current for one hour (3200mA x 1hr = 3200mAh), etc. Very large batteries, such as lead-acid field batteries, are usually rated in “Ah” or amp-hours. A “12V 7A” field battery can deliver 7 amps of current for onehour (7A x 1hr = 7Ah).

“C” rating: Capacity is also referred to as the “C” rating. Some battery suppliers recommend charge and discharge currentsbased on the battery’s “C” rating. A battery’s “1C” current value is the same number as the battery’s rated capacity number,but noted in mA or amps. A 600mAh battery has a 1C current value of 600mA…a 3C current value of (3 x 600mA) 1800mA.The 1C current value for a 3200mAh battery would be 3200mA (3.2A), etc.

GLOSSARY OF TERMS

4

Triton Jr. only accepts DC input power which could come from a 12V power supply or 12V automotive battery. It’s best to usea clean DC power source whose output is filtered to remove unwanted electrical noise. Do NOT use an automobile batterycharger as a power source. To achieve the absolute maximum output power, the power source must be capable of deliveringat least 6.5 amps of current while maintaining 12 volts DC.

The input power lead is located on the left side of the charger. Securely connect the charger’s red alligator clip to the positive(+) terminal on the power source, and the black alligator clip to the negative (-) terminal. WARNING! NEVER allow the redand black input connections to touch each other while connected to 12V DC power. Failure to do so could result inpermanent damage to the power source and the charger. It’s recommended to disconnect the charger from inputpower when not in use.

The charger is always on when connected to the power source (there isn’t any ON/OFF power switch). Therefore, disconnectthe charger from input power when not in use. If input power is below 11.0V or above 15.0V, the display will show an “Inputvoltage” error. If this occurs, re-check the input power supply to ensure adequate power is present.

A 10 amp auto, or spade type fuse is located on the left side of the charger, and is used to protect the charger’s input. If yoususpect the fuse has blown, be sure to first disconnect the charger from input power. Then, remove and inspect the elementinside the fuse. If the element is burnt, replace the fuse with a new fuse of the exact same rating. Do NOT use a fuse withrating greater than 10A.

Triton Jr. has a maximum overall power rating of 63 watts. If trying to charge a high voltage battery at high current, the chargermight deliberately reduce the output current to keep the output power under the maximum level. This is normal, and designedto protect the charger.

It is always CRUCIAL to know your battery’s exact type, rated voltage and capacity!! Failure to know these points is oneof the biggest reasons why batteries fail. A few short minutes learning the basics of battery care can easily preventunnecessary crashes (and lost money!). Carefully read your battery’s label and/or instruction sheet or consult your batterysupplier and determine:

1. Is the battery type nickel-cadmium (NiCd), nickel-metal hydride (NiMH), lithium-polymer (LiPo), lithium-ion (Li-Ion), or lead-acid (Pb)?

2. What is the battery’s total rated capacity? The mAh or Ah rating should be listed directly on the battery’s label. If not,consult your battery supplier.

3. What is the battery’s nominal rated voltage? NEVER guess the rated voltage of a LiPo or Li-Ion battery! If not printedon the battery’s label, consult your battery supplier or determine pack voltage as follows:

A. NiCd and NiMH: multiply the total number of cells in the pack by 1.20. A 6-cell pack will have a nominal voltage of7.20 volts (6 x 1.20). An 8-cell pack will have a nominal voltage of 9.60 volts (8 x 1.20), etc.

B. LiPo: multiply the total number of cells in the pack by 3.70. A 2-cell LiPo wired in series will have a nominal voltageof 7.4V (3.7 x 2). A 3-cell LiPo wired in series will have a nominal voltage of 11.1 volts (3 x 3.70), etc.

C. Li-Ion: multiply the total number of cells in the pack by 3.60. A 2-cell Li-Ion wired in series will have a nominal voltageof 7.20 volts (2 x 3.60). A 3-cell Li-Ion wired in series will have a nominal voltage of 10.8 volts (3 x 3.60), etc.

DETERMINING BATTERY TYPE & SPECIFICATIONS

All main functions (charge, discharge, cycle) for all battery types are conveniently found in the Main Menu. Starting allfunctions is done within this menu as well. Refer to the included flowchart when using the Main Menu. Going left to right, thismenu includes all functions for NiCd batteries, then NiMH, LiPo (and Li-Ion), and lead-acid batteries (Pb). More specificinformation about settings for each battery type is included in separate flowcharts for each battery type (which are still part ofthe Main Menu).

IMPORTANT: Different parameters exist for each battery types, so it‘s CRUCIAL to use functions in the menu whichare marked for your exact battery type!!

When power is applied, Triton Jr. will automatically default to the “NiCd CHARGE” screen (top-left of Main Menu flowchart). Tochange battery types, press BATT TYPE until the proper battery type is found (moving right across the flowchart). Select fromNiMH, LiPo (Li-Ion settings are found in this screen also), and Pb (lead-acid).

ALWAYS connect the charge lead to the charger FIRST, with the red positive (+) lead connected to the red jack, and the black negative(-) lead to the black jack. Then, connect the battery to the charge lead. See the ERROR INDICATIONS AND SAFETY FEATURESsection at the rear of this manual if errors are indicated regarding the connection of the battery to the charger’s output.

WARNING! NEVER allow the positive and negative output connections to touch while a battery is connected to theoutput. Failure to do so could result in permanent damage to the battery and/or the charger and void your warranty.

CARE AND HANDLING INSTRUCTIONS FOR NIMH BATTERIES

• NEVER allow NiMH batteries to overheat, as this could adversely affect their performance. If this happens, disconnectthe battery from the charger immediately and allow to cool!

• NEVER deep cycle NiMH batteries as permanent damage could result.• NEVER attempt to use the NiCd, Pb, or lithium functions with NiMH batteries.• Store NiMH packs with some voltage remaining on the cells (refer to battery supplier).

CHARGE TIPS:Using a current which couldfully charge an empty pack in 1to 2 hours should avoidoverheating of the battery. Thistable shows recommended 1and 2 hour charge currentsettings for batteries of differentrated capacities.

DISCHARGE TIPS:More accurate mAhmeasurements can be achievedwhen using a current which candischarge the pack in 1 or 2hours, as shown in this table.Note: The maximum dischargecurrent is 1 amp. And, themaximum power dissipationduring discharge is 5 watts,which might cause dischargecurrents to automatically belimited for packs having high voltage.

Charge capacity: This is how much capacity (energy, in "mAh") has been delivered to the pack during charge. For a battery which previously had some charge, this number could be low. For a battery which previously had little or no charge, this number should be higher (ideally within 10% of the battery's own mAh rating).

Elapsed charge time: This is the number of minutes the battery has been on charge. For a battery which previously had some charge, this number could be low. For a battery which previously had little charge, this number should be larger.

NOTES FOR CHARGING NiCd & NiMH BATTERIES• A battery which is approaching- or has reached full charge should become

warm to the touch, but never get HOT. If overheated, the battery has likelyreached an overcharge condition and should be disconnected from thecharger immediately!! Allow the battery to cool before use.

• Lower current means it takes longer to charge, but it’s less stressful on thebatteries, tends to result in more fully charged batteries, and helps tomaximize the battery’s lifespan.

• Larger “sub-C” size cells can handle peak charge currents up to 5.0 ampswith little heat generation. Smaller “A” and “AA” cells overheat more easilyand should be charged at much lower currents. Even smaller “AAA” and“N” cells should be charged at lower rates. Refer to the table above forrecommended charge currents.

• For packs having more than 8 cells, the actual amount of current deliveredto the battery might be limited due to the charger’s maximum rated outputpower. This is normal.

• To keep NiCd batteries in good operating condition, it’s a good idea toproperly discharge them before charging on a regular basis.

• NiMH batteries have a self-discharge rate of about 20-25% (vs. 15% forNiCd). Always recharge NiMH batteries just prior to use.

• The “deltaV” peak detection method is used to charge NiCd and NiMHbatteries up to 95-98% full charge. A trickle charge current willautomatically be delivered to the battery after peak charge ends. Thistrickle charge is designed to help the battery safely reach 100% fullcharge. Trickle charge is applied only after an individual peak charge (notafter discharge or cycle), and will remain on until the pack is disconnected.The trickle current value is fixed at a rate being the regular charge currentsetting divided by 20. A fast charge current of 1.0A will result in a tricklecurrent setting of (1000mA / 20) 50mA. A fast charge current of 600mAwill result in a trickle current of (600 / 20) 30mA, etc.

• Charge can be stopped manually by pressing ENTER, or disconnectingthe pack.

• A backup safety timer will also stop charge if not completed after 1.5 hours.

WARNING! It is normal for NiCd and NiMH batteries to become warm during charge. Disconnect batteries IMMEDIATELY if theybecome hot at any time! If batteries become overheated, it may be necessary to use a lower charge current in the future. Neverattempt to charge batteries at excessive rates, as permanent damage could result.

1. At the default “NiCd CHARGE” screen, to discharge a NiCd battery press the down arrow to find the “NiCdDISCHARGE” screen and skip to step 3.

2. To discharge a NiMH battery, press BATT TYPE twice to find the “NiMH CHARGE” screen. Then press the downarrow to find the “NiMH DISCHARGE” screen.

3. Two values can be adjusted in the discharge screen. Press ENTER to cause the discharge current value to flash.Press INC+ or DEC- to change this value (0.1 – 1.0 amps). See the chart on page 9 for recommended dischargecurrent settings. Note that “0.4A” is the same as 400mA…”0.9A” is the same as 900mA, etc. Press ENTER to causethe voltage value to flash, which is the voltage of the entire pack (not per cell) where discharge will end. Press INC+or DEC- to adjust this value as desired. NiCd and NiMH cell manufacturers recommend discharging batteries downto 1.0-1.1V per cell. See the “Discharge Cutoff Settings” chart at right to determine the discharge cutoff point foryour battery. Once set, press ENTER, or wait 5 seconds and Triton Jr. will automatically confirm both settings.

4. To START DISCHARGE, press and hold START for 2 seconds. The “BATTERY CHECK, PLEASE WAIT…”display will show briefly as Triton Jr. evaluates the condition of the battery. If the battery is ready, discharge willstart automatically at which time you’ll see a screen like the one on the right.

5. When discharge is finished, the screen will show “END”and tones will sound for 10 seconds. The battery can nowbe re-charged, or disconnected from Triton Jr. Other datameasured during discharge can be viewed in the DATAVIEW screens, as shown on page 20.

DISCHARGE CAPACITY: This how much energy (capacity in “mAh”) that has been taken from the battery during discharge. For a battery which previously had little charge, this number could be low. For a battery which previously had been fully charged, this number should be high (ideally within 10% of the battery’s own mAh rating).

ELAPSED DISCHARGE TIME: This is the number of minutes the battery has been on discharge. For a battery which previously had little charge, this number should be low. For batteries which previously had been fully charged, this number should be larger.

NOTES FOR DISCHARGING NiCd & NiMH BATTERIES• Some transmitters might contain a diode in their charge circuit which could prevent the Tx battery

from being discharged through the radio’s charge jack. In such case, a “No battery” error will show.It’s best to remove the battery from the Tx and connect it directly to Triton Jr. for discharging. (seepage 6 for a list of adapters).

• For more accurate discharge readings, it’s better to use a current which can discharge the pack in1 or 2 hours.

• The maximum discharge current is 1 amp.Maximum power dissipation during discharge is 5 watts,which might cause discharge currents to automatically be limited for packs having high voltage.

• Sub-C and some “A” size cells are often used for high current/power applications such as drivingelectric motors (not for radio system uses). These applications typically result in cells beingdischarged to voltages below 1.1V per cell. To determine the condition of these cells, it may bedesirable to set the discharge cutoff voltage to 0.9V per cell (multiply number of cells in the packby 0.9). Do NOT attempt to discharge cells to voltages lower than recommended.

• To determine the condition of a battery, compare the final capacity measurement the batterydelivered during discharge to the capacity rating listed on the battery’s label. If a battery providesless than 70% of its rated capacity it may need to be replaced. Additional cycles can be attemptedto try and revive the battery, but if capacity measurements fail to improve the battery should bereplaced.

• Discharge can be stopped manually by pressing ENTER, or disconnecting the pack.

Battery “cycling” is the process of fully charging then discharginga battery to a pre-determined cutoff point (or vise-versa). Cyclingis only recommended for NiCd and NiMH batteries, and never forlithium or lead-acid batteries. Triton Jr. can perform anywhere fromone to five cycles consecutively.

1. First, determine if you want the battery to be discharged firstfollowed by a peak charge (this is sometimes preferred if the batteryis used on a regular basis). Or, do you prefer to peak charge thebattery first followed by a discharge (sometimes preferred if thebattery is new or has not been used for some time).

2. At the default “NiCd CHARGE” screen, to cycle a NiMH batteryskip to step 3. To cycle a NiCd battery press the down arrow tofind either the “NiCd CHG TO DSCH” or “NiCd DSCH TO CHG”screen (depending if you want to charge or discharge first) andskip to step 4.

3. Press BATT TYPE twice to find the “NiMH CHARGE” screen.Press the down arrow to find the “NiMH CHG TO DSCH” or“NiMH DSCH TO CHG” screen (depending if you want tocharge or discharge first).

4. Press ENTER to cause the first current value to flash. It’s very important to note whether this is the charge (CHG) ordischarge (DSCH) current! Press INC+ or DEC- to adjust this current as desired. Press ENTER to select the next currentvalue, and adjust it with the INC+ or DEC- buttons if desired. See the table on page 9 for recommended charge anddischarge currents. Press ENTER, or wait 5 seconds and Triton Jr. will automatically confirm both settings.

5. Press ENTER until the cycle number “1X” starts to flash. This setting determines how many cycles will be performedconsecutively. Press INC+ or DEC- to adjust this current as desired. Press ENTER, or wait 5 seconds and Triton Jr. willautomatically confirm this setting.

CYCLING NiCd & NiMH BATTERIES

12

NOTES FOR CYCLING NiCd & NiMH BATTERIES• Periodic cycling of NiCd batteries (once every month or two) can be

beneficial in keeping them in good operating condition. Excessivecycling (more than once monthly) will unnecessarily shorten thelifespan of the battery.

• A short time delay of 3 minutes will occur in-between thecharge/discharge functions to allow the battery to cool. This is normal,and cannot be changed.

• During cycle mode, the discharge cutoff voltage for NiCd and NiMHbatteries is FIXED (not adjustable) at 0.8V per cell.

• Cell manufacturers note three main benefits of cycling NiCd and NiMH batteries:

1. Battery maintenance: NiCd batteries benefit the most from regularcycling to help keep them in good operating condition, and isrecommended once monthly. NiMH batteries do not require asmuch cycling.

2. Determining battery condition: NiCd and NiMH batteries are ratedby how much charge energy or “capacity” they can store comparedto their rated capacity. A battery that can supply only a smallfraction of its rated capacity is likely reaching the end of its usefullife and may need to be replaced.

3. Breaking-in batteries: new NiCd and NiMH batteries may need tobe broken-in before they will perform to their specifications. Olderbatteries which have been unused for an extended length of timemay require to be broken-in again to regain their usefulness.Repeated cycling is the best way to revive such batteries.

6. To START CYCLING, press and hold START for 2 seconds.“BATTERY CHECK, PLEASE WAIT…” will show briefly, andTriton Jr. will start cycling if the battery is in suitable condition,at which time you’ll see a screen as shown to the right .

7. When all cycling is finished, “END” will show on-screen. PressBATT TYPE to see the DATA VIEW screens for final cyclinginformation (go to page 20). Note that Triton Jr. will only showdata for the last cycle (not all cycles). If set to cycle 4 times, onlydata for cycle 4 will be viewable (not for cycles 1, 2, or 3).

WARNING!! NEVER ATTEMPT TO CARE FOR LITHIUM-POLYMER (LiPo) OR LITHIUM-ION (Li-Ion) CELLS IN THE SAMEWAY AS OTHER BATTERY TYPES! LiPo and Li-Ion cells are much more sensitive and volatile than NiCd, NiMH or lead-acidbatteries. Misuse and overcharge can quickly result in LiPo/Ion cells getting hot and/or swelling, which could lead to VIOLENTEXPLOSION AND/OR FIRE and serious personal injury and property damage. Do not mistake LiPo cells for other lithium-based cell types (such as lithium-metal), as different lithium hybrids have different care and handling characteristics as well.All “lithium” based batteries types are NOT exactly the same.

• NEVER leave lithium batteries unattended during charge.• NEVER place lithium batteries on combustible surfaces during charge.• NEVER attempt to use the NiCd, NiMH, or Pb functions with lithium batteries.• NEVER continue to charge or use LiPo/Ion cells if they start to swell, become overly warm to the touch, or if they do not charge

within the specified charging time. Failure to follow this guideline could cause the battery to become hot, and explode or ignite!!• NEVER discharge Li-Ion cells lower than 2.5V per cell.• LiPo/Ion cells have an 8% self discharge rate, meaning they can hold charge very well. Thus, there is no need to trickle

charge LiPo/Ion cells. No cycling of lithium batteries is needed.• LiPo/Ion cells should be charged about once per year at a minimum to prevent over-discharge.• LiPo/Ion batteries should be stored with about 30%-50% of capacity.• If LiPo/Ion cells leak fluid, rinse the affected area well with water and seek immediate medical care.

Triton Jr. can handle lithium-polymer (LiPo) and lithium-ion (Li-Ion) battery types. While similar in many ways, there are some slightdifferences in these two battery types. Setting Triton Jr. for the proper lithium type is necessary for safety, and will result in better performancefor your packs. Refer to the Lithium Menu flowchart included.

1.The default setting is for Triton Jr. to handle LiPo batteries. If you will be using LiPo batteries only, skip the remainder of this section.

2. To change Triton Jr. to handle Li-Ion batteries, at the default “NiCd CHARGE” screen press BATT TYPE three times to find the “LiPoCHARGE” screen. Press the down arrow twice to find the “Lithium type” screen.

3. Press ENTER, then either INC+ or DEC- to change from LiPo to Li-Ion.

4. Press ENTER, or wait 5 seconds and the new battery type will automatically be confirmed. All screens and settings relating to lithiumbatteries will now be for lithium-ion cells. Press the up arrow twice to find the “Li-Ion CHARGE” screen.

LiPo packs are commonly available in two different assembly/wiring configurations: wired for balancing, and for non-balancing. It is veryimportant to know exactly which types of packs you have before proceeding. Consult your battery supplier if you are unsure if yourbattery is or is not wired for balancing, and whether it has a built-in safety circuit.

NON-BALANCED packs are wired so that all cells are charged at the same time, regardless of the condition of individual cells. These typesof packs have a charge lead with two wires that are connected to the first and last cell in the pack. Sometimes these packs might have abuilt-in charge safety circuit, as do many ElectriFly brand packs (with SafeCharge™), which prevents cells in thepack from being overcharged but this is NOT the same thing as “balancing”.

Packs wired for BALANCING normally have a unique connector which has more than two wires going to the pack itself.Each wire is connected to individual cells inside the pack, by which a charger or discharger can monitor the voltage ofevery cell individually and control whether each cell should be charged or discharged. All ElectriFly brand packs whichare wired for balancing have a plug like shown at right. Packs wired for balancing MUST be charged with a LiPo chargerthat is capable of balancing, or by using a LiPo charger with a LiPo cell balancer such as the Equinox™ LiPo Cell Balancer(GPMM3160) from ElectriFly. Triton Jr. is 100% compatible with the Equinox LiPo cell balancer.

WARNING! Always follow the instructions below when charging LiPo/Ionbatteries! LiPo/Ion batteries should NEVER get warm anytime duringcharge! Disconnect batteries IMMEDIATELY if they become excessivelywarm or hot at any time, and refer to the Troubleshooting Guide in therear of this manual for details. LiPo/Ion cells are much more dangerousthan NiCd or NiMH batteries, and pose a significant FIRE HAZARDwhich can result in causing bodily harm and/or permanent damage to thecells and the surrounding environment.

1. At the “NiCd CHARGE” screen, press BATT TYPE three times to findthe “LiPo CHARGE” screen (or “Li-Ion CHARGE” screen if you selectedthat lithium type).

2. Two values MUST be properly set in this charge screen. Instead ofshowing a charge current value, Triton Jr. shows a battery capacityvalue (default is “350mAh”). Press ENTER to cause this value to flash.Then press INC+ or DEC- to find the capacity value that most closelymatches the capacity rating marked on your lithium battery. Triton Jr.will then set the charge current for your battery automatically (seenotes section for details).

3. Press ENTER to cause the voltage value to flash. Press INC+ or DEC-to set this voltage to the exact nominal voltage rating shown on yourpack. Press ENTER, or wait 5 seconds and Triton Jr. will automaticallyconfirm both settings.

WARNING!! NEVER enter a capacity or voltage number that is higher than the value specified for your battery! Failure to follow this warningcan cause permanent damage to your battery, charger and surroundings in the form of FIRE!

4. To START CHARGE, press and hold START for 2 seconds. “BATTERY CHECK, PLEASE WAIT…” will show briefly, and Triton Jr. will startcharging if the battery is in suitable condition.

5. When finished charging, the screen will show “END” and tones will sound for 10 seconds. The battery should now be ready for use. TritonJr. will display details about the charge data for your battery, including charge capacity, elapsed charge time, etc. Other data measuredduring charge can be viewed in the DATA VIEW screens shown on page 20.

CHARGING LiPo OR Li-Ion BATTERIES

15

NOTES FOR CHARGING LiPo & Li-Ion BATTERIES• Triton Jr. automatically sets the charge current based on the battery’s 1C

rating. Therefore, it is very important to enter the battery’s exact ratedcapacity (in mAh) in the programming. For example, if a capacity of600mAh is entered Triton Jr. will set the charge current at 0.6A (600mA).For a capacity setting of 2500mAh, the charge current will be set to 2.5A(2500mA). If you do not change the factory default battery capacity value,Triton Jr. will charge the battery as if it’s rated at 350mA (0.35A).

• LiPo and Li-Ion batteries are charged using the “constant current /constant voltage” process (cc/cv). Constant current is delivered during thefirst part of fast charge. As the battery reaches a pre-set voltage, Triton Jr.shuts off constant current and starts to apply a constant voltage. As thebattery’s voltage equalizes to the output voltage of the charger, the chargecurrent will drop to a value equal to the battery’s rated capacity divided by10, and then automatically stop charge as the battery is fully charged.

• During charge, it’s possible that current to the battery might NOT reachthe full value as set in the programming. This is because Triton Jr.constantly monitors the condition of the battery and makes sure not todeliver more current than the battery can handle at any given time. This isnormal.

• LiPo/Ion batteries do not need trickle charge, and therefore no suchfunction exists.

• For LiPo/Ion batteries rated at 11.1V or greater, the actual amount ofcurrent delivered to the battery might be limited due to the charger’smaximum rated output power. This is normal, due to various possiblecircumstances such as the condition of the battery, limitations of the inputpower source, charge connector, etc.

• For safety reasons, fast charge of LiPo/Ion batteries will automaticallystop if the actual amount of capacity delivered to the battery reaches110% of the capacity setting entered in point 2.

• A backup safety timer will also stop charge if not completed after 2 hours.

1. At the “LiPo CHARGE” screen (or “Li-Ion CHARGE” screen ifyou selected that lithium type), press the down arrow once tofind the “LiPo DISCHARGE” screen (or “Li-Ion DISCHARGEscreen if you selected that lithium type).

2.Two values can be adjusted on this discharge screen. Press ENTER to cause the discharge current value to flash. Press INC+ orDEC- to change this value (0.10 – 1.0 amps). Note: “0.1A” is the same as 100mA. “0.8” is the same as 800mA, etc.

3. Press ENTER to cause the discharge cutoff voltage value to flash. This is the voltage where Triton Jr. will stop dischargingthe battery, and is based on 3.0V per cell. So the cutoff voltages should be 3.0V for a 1-cell battery, 6.0V for 2-cell packs,9.0V for 3-cell packs, and 12.0V for 4-cell packs. Press INC+ or DEC- to adjust this value as needed. Press ENTER, or wait5 seconds and Triton Jr. will automatically confirm both settings.

4. To START DISCHARGE, press and hold START for 2 seconds. “BATTERY CHECK, PLEASE WAIT…” will show briefly, andTriton Jr. will start discharging if the battery is in suitable condition.

5. When discharge is finished, the screen will show “END” and tones will sound for 10 seconds. The battery can now be re-charged, or disconnected from Triton Jr. Other data measured during discharge can be viewed in the DATA VIEW screensshown on page 20.

Never attempt to care for lead-acid (Pb) batteries in the same way as other battery types! Lead-acid batteries commonly usedin R/C hobby field boxes require unique care and handling methods as they contain different characteristics than other battery types.• Do not attempt to use the NiCd, NiMH, or lithium functions on Pb batteries.• Do not exceed 14.7V maximum charge voltage for batteries rated at 12V.• Pb batteries have a self-discharge rate of 5-10%, meaning they hold charge very well. Thus, there is no need to trickle

charge Pb batteries. No cycling of Pb batteries is needed.• Do not leave Pb batteries in the full discharge condition, which could cause the battery to lose its ability to regain full charge.

CARE & HANDLING FOR LEAD-ACID BATTERIES (Pb)

DISCHARGING LiPo OR Li-Ion BATTERIES

16

NOTES FOR DISCHARGING LiPo AND Li-Ion BATTERIES• For more accurate discharge readings, it’s better to use a current which

can discharge the pack in 1 or 2 hours.

• The maximum discharge current is 1 amp. Maximum power dissipationduring discharge is 5 watts, which might cause discharge currents toautomatically be limited for packs having high voltage.

1. At the default “NiCd CHARGE” screen, press BATT TYPE fourtimes to find the “Pb CHARGE” screen.

2.Two values can be adjusted on the Pb charge screen. PressENTER to cause the charge current value to flash. Press INC+ orDEC- to change this value (0.1 – 5.0 amps).Note:“0.1A” is the sameas 100mA. “0.8” is the same as 800mA, etc. For 12V 7Ah lead-acidfield batteries, a charge current of 0.5A to 1.0A should safely, fullycharge a battery in 7 to 14 hours.

3. Press ENTER to cause the voltage value to flash. Most hobby fieldbatteries have a nominal rated voltage of 12V.Make sure the voltagemarked on the battery matches the voltage setting on-screen. Tochange this value, press INC+ or DEC-. Press ENTER, or wait 5seconds and Triton Jr. will automatically confirm both settings.

4. To START CHARGE, press and hold START for 2 seconds.“BATTERY CHECK, PLEASE WAIT…” will show briefly, andTriton Jr. will start charging if the battery is in suitable condition.

5. When finished charging, the screen will show “END” and toneswill sound for 10 seconds. The battery should now be ready foruse. Triton Jr. will display details about the charge data for yourbattery, including charge capacity, elapsed charge time, etc.Other data measured during charge can be viewed in the DATAVIEW screens shown on page 20.

CHARGING Pb (LEAD-ACID) BATTERIES

17

NOTES FOR CHARGING Pb BATTERIES• Lead-acid batteries use the “constant current / constant voltage”

method (cc/cv) as explained in the section for lithium batteries.However, different voltage levels are used for evaluating the conditionof Pb batteries.

• Lead-acid batteries do not need trickle charge, and therefore no suchfeature exists.

• Lead-acid batteries have a nominal voltage of 2.0V per cell. For mostfield batteries, even though you cannot see any individual “cells”,there are 6 cells internally. At 2.0V per cell, this makes a total fieldbattery voltage of 12V.

• For lead-acid batteries rated at 12V or greater, the actual amount ofcurrent delivered to the battery might be limited due to the charger’smaximum rated output power. This is normal, due to various possiblecircumstances such as the condition of the battery, limitations of theinput power source, charge connector/connection, etc.

1. At the “Pb CHARGE” screen, press the down arrow once to findthe “Pb DISCHARGE” screen.

2. Two values can be adjusted on this discharge screen. PressENTER to cause the discharge current value to flash. PressINC+ or DEC- to change this value (0.10 – 1.0 amps).

3. Press ENTER to cause the voltage value to flash. This is thebattery’s minimum discharge cutoff voltage, based on 1.8V percell. Since most hobby batteries have a nominal voltage of 12V(6 cells), the proper discharge cutoff voltage would be (1.8V x6) 10.8V. Press INC+ or DEC- to adjust this value if necessary.Press ENTER, or wait 5 seconds and Triton Jr. will automaticallyconfirm both settings.

4. To START DISCHARGE, press and hold START for 2 seconds.“BATTERY CHECK, PLEASE WAIT..” will show briefly, andTriton jr. will start discharging if the battery is in suitablecondition.

5.When discharge is finished, the screen will show “END” and tones willsound for 10 seconds. The battery can now be re-charged, ordisconnected from Triton Jr. Other data measured during dischargecan be viewed in the DATA VIEW screens shown on page 20.

DISCHARGING Pb BATTERIES

18

NOTES FOR DISCHARGING Pb BATTERIES• For more accurate discharge readings, it’s better to use a current

which can discharge the pack in 1 or 2 hours.• The maximum discharge current is 1 amp. Maximum power

dissipation during discharge is 5 watts, which might cause dischargecurrents to automatically be limited for packs having high voltage.

• The proper discharge cutoff voltage for batteries with a nominal ratedvoltage of 2V is 1.8V, 4V batteries should be discharged to 3.6V, 6Vbatteries should be discharged to 5.4V, 8V batteries should bedischarged to 7.2V, and 10V batteries should be discharged to 9V.

An audible BUZZER identifies when a function has started or stopped. The buzzer also alerts the user when an error has occurred. Thebuzzer will also sound once for each push of a button to aid in setting up the charger.This buzzer cannot be adjusted or turned off.

When settings are adjusted in the programming, Triton Jr. will memorize these settings until changed again manually. Thissingle MEMORY should retain all settings even when power is removed from the charger (but all test data will be lost whenpower is removed).

A backup SAFETY TIMER feature is designed to protect the charger, battery, and surrounding environment during charge. IF for somereason Triton Jr. does not properly identify a battery having reached full charge (peak for NiCd/MH batteries) the backup safety timershould automatically shut off charger to prevent any damage from occurring due to overcharge.The safety timer settings are 1.5 hours(90 minutes) for NiCd and NiMH batteries, and 2 hours (120 minutes) for LiPo and Li-Ion batteries.

At the beginning of charge the voltage for NiCd and NiMH batteries can be somewhat unstable. This instability could possibly causethe peak detection circuitry to accidentally trip and stop charge, which would cause the battery to NOT become properly charged. Toavoid this, Triton Jr. uses a PEAK DELAY AT START function whereby the peak detection circuit is automatically turned of during thefirst 3 minutes of charge.After 3 minutes, the peak detection circuitry will automatically turn on and allow Triton Jr. to properly, accuratelydetect peak when it actually occurs.The “peak detection” circuit automatically stops delivering charge to NiCd and NiMH batteries whenTriton Jr. actually sees that the battery’s voltage actually drops very slightly just after full charge has been reached.The charger’s abilityto identify this very tiny voltage is called PEAK SENSITIVITY.Triton Jr. is set to have a 8mV per cell peak sensitivity for NiCd batteries,and 5mV per cell for NiMH batteries. These sensitivity settings are not adjustable.

Holes are designed in the case to allow hot air to escape to help keep the electronic circuitry cool. This helps to maintainaccurate operation and maximize the lifespan of the charger itself. CAUTION: Do not block the vent holes during operation,as it could cause the charger to overheat and possibly cause permanent damage.

ERROR INDICATIONS AND SAFETY FEATURES

Triton Jr. uses solid-state circuitry to protect against potential damage which could be caused by short-circuit or reversepolarity conditions. If power is connected backwards to Triton Jr.’s input, the screen may turn black and no other operationwill occur, but it will be protected from damage. Re-check all input connections to make sure it is connected properly.

The following warning / error messages are designed to show on-screen to protect the charger and battery from damagedue to improper connection, input voltage, etc. These messages will be accompanied by lout tones on the buzzer. Whenany message appears, refer to the corresponding problem and solution explanation. Press ENTER to clear the warning.

ERROR DISPLAYED PROBLEM AND SOLUTION“Input voltage” When input voltage is under 11.0V or over 15V.“No battery” When a battery is not detected at the charger’s output.“Open circuit” When a battery becomes disconnected while a function is in progress.“Reverse polarity” When a battery is connected to the output in reverse.“Overheating” The temperature inside the charger’s case is too high. Triton Jr. will pause the current function and

show this message. The function will resume automatically after the charger has cooled to anacceptable level.

“Time limit over” When the charge safety timer has expired (1.5 hours for NiCd/MH, and 2 hours for LiPo/Ion batteries).“Internal error” When a problem exists within the control circuitry of the charger.“Batt volts too high” When the voltage setting in the charger is too low.

PROBLEM: Display does not work when unit. Check power supply for proper power. Check input connections for proper contact.

PROBLEM: Charger doesn’t recognize battery. Make sure battery is not connected backwards. Check for faulty connectionor wiring. Perhaps there is a defective cell in the pack, in which case the pack should be replaced.

PROBLEM: Does not automatically stop charge after 1.5 hours for NiCd/MH batteries, or 2 hours for LiPo/Ion batteries.Internal problem might exist. Disconnect battery IMMEDIATELY and contact Hobby Services.

PROBLEM: Battery voltage low after charge is completed. Make sure charge current setting isn’t too low. Battery might be defectiveand require replacement.Check to see if the backup safety timer expired before full charge was reached.For lithium batteries, makesure the battery capacity value entered in the programming matches the rated capacity of the battery.

PROBLEM: Will not lock into discharge mode. An improper discharge voltage was entered for the battery. Adjust the batteryvoltage in the discharge screen to match the number of cells in the pack. Tx might have a diode in charge circuit, in whichcase it’s best to connect the battery to the charger directly (outside of the Tx). Battery might be defective and requirereplacement. Battery might already be discharged.

PROBLEM: Low mAh readings after discharge. Batteries might not have been fully charged prior to discharge. Batteriesmight have been old or unused for an extended period of time, which may require additional cycles to see if capacityimproves. Battery might be defective and require replacement. Discharge current setting might be too high, and should belowered. An improper discharge voltage was entered for the battery. Adjust the battery voltage to the proper value for thebattery. Battery might already be discharged.
